The Extension of the Natural-Number Domain to the Integers in the Transition from Arithmetic to Algebra.
Gallardo, Aurora
Educational Studies in Mathematics, v49 n2 p171-92 2002
Analyzes from an historical perspective the extension of the natural-number domain to integers in students' transition from arithmetic to algebra in the context of word problems. Extracts four levels of acceptance of these numbers--subtrahend, relative number, isolated number and formal negative number--from historical texts. The first three levels were observed among 35 12-13-year-old students. (Author/MM)
